Kid-friendly London activities?

If they liked Harry Potter you could try this:

Check into the Science Museum...

Riding on the top floor of the double-decker buses! Also I second the Harry Potter Studios tour.

Here's a good article from Time Out London:

The slides at Victoria Park look good to me.

Thanks!! I will check into these!

Take the water taxi (I forget what they call em in London) out the Thames to Greenwich to see the Royal Observatory, Cutty Sark, and some other great stuff. Depending on the seven year old, I would think the London Eye would be fascinating, though maybe too long time-wise.

There's the Museum of Childhood in Bethnal Green which is an outpost of London's main Victoria and Albert arts and crafts museum. Another possibility is Pollock's Toy Museum.

Here is what my kids have like during Dec in London:

• Hyde Park Winter Wonderland
• Boat ride from Westminster to Greenwich
• London Eye
• Hamleys (Toy store)
• Museums: British, V&A, Natural History, Science
• Tower of London

Edit: the Diana playground in Hyde Park is great for kids (NW corner of the park) but unless the weather is spectacular in Dec I wouldn't go there.

I took my kids to London a couple of years ago. They were ages 5 and 7 at the time, so these ideas are perhaps geared more towards your son. Anyway, here are some things they liked - omitting the big sites:

1. London Transportation Museum - This has lots of old buses, subways, etc. to play on. It is at Covent Garden which has lots of interesting street performers to watch. There are also theaters nearby - we saw the Lion King and loved it.

2. Windsor Castle - This is an easy day trip to an interesting castle. One other day trip option is Hampton Court. I haven't been, but I've heard very good things.

3. Diana Playground (Hyde Park)

4. V&A, Natural History and Science Museums - all free and right next to each other in South Kensington. The Natural History museum has dinosaurs. The Science Museum has lots of hands on exhibits and a great staff. The V&A has a random mix of interesting things and interactive kiosks that my girls liked.

5. Royal Mews - some horses and lots of carriages. The changing of the horse guards near St. James is also interesting, especially if your kids like horses.

6. Churchill War Rooms - a surprise hit with my kids. They liked the kid-specific audio tour, especially in the Churchill Museum portion.

7. St. Martins - near Trafalgar Square. A unique place to have an adequate lunch (in the crypts). You can make rubbings, so your kids can create a self-made souvenir.

8. High Tea - we went to the Orangery, but there are lots of options around town.

I'm assuming that you're seeing the Tower of London, Westminster Abbey, London Eye, the British Museum, etc. with your entire group.

Good luck and have fun with whatever you decide!

Mudchute Farm http://www.mudchute.org. Natural History Museum (who doesn't like dinosaur bones?) Ice skating rinks, (there's usually one outside the Natural History Museum) visit Harrod's food halls, try to get tickets to a Pantomime (http://www.timeout.com/london/theatre/christmas-pantomimes-in-london), Ride bikes in Hyde Park. Feed the waterfowl at the Round Pound in Kensington Gardens. See if Tower Bridge is scheduled to open for a passing ship. http://www.towerbridge.org.uk/lift-times/ or if not afraid of heights enjoy the Tower Bridge Exhibition. Enjoy.

Ooh good ideas!
What about the London Zoo? Is that a good thing to visit in December (may seem a silly question, but I am from Florida so we have a different idea of winter!)?
